filo. s'rones;

To all whom it may concern: I, Be itknown that I, ALBERT MATHEWS, a citizen of the United States, and a resident of the city of- New Y o'rk,borough of Brooklyn, in thecounty of Kings and State of New York, have inveiited a new and Improved- Attachment for Air-Ships, .of which the following is a full, clear, and exact description.' 1 a a This-invention is designed to be applied to-air ships suitable propelling and steering mechanism, 10 and has for itsobject to provide mechanism simple and light in'structure and efiective in operation, for the purpose of elevating the device to which it is applied. 'In the accompanying drawings, which illustrate my invention in its preferred form, Figure 1 is'a side ele- 15' vation of a device embodying my invention applied to a main frame; and Fig.2 is a plan of the same.

' a As illustrated in the'dr awings, 1 represents a platform having a rail 2 extending around the edge thereof, l and a motor 3 of any suitable construction supported on said platform. .The motor is provided with a drivshaft 4 upon which aremounted beveled gears 5 with corresponding gears 6 attached to the lower ends of upright'shafts 7, which shafts are sup-j ported in bearings formed'on cross bars 8 and'9 respec 2 5 1-tively, attached'to standards 110. Radial arms llare inounted upon thenpper ends of the shafts 7, and provided on their outer ends'with buckets each having a curved w'all 12 entending in a quarter circle, and sectorends 13; The buckets may be mounted upon the ra- F 11 in any suitable .manner, but as shown -';herein.thearins extend through the oppositely'dis- Specification of Letters Patent. Application filed March 16. 1907.v Sierial No. $62,643.

Patented Ngmb, 1907 posed end walls of each of the buckets so as to combine strength and lightness in said parts. When the device is in use the drive shaft 4 rotates the vertical shafts 7, the'radial arms 11, and the buckets mounted thereon-.-

The buckets are driven against and gather in the air I as they move forward and exert a downward pressure on the air by reason of their curv'ed top and back,

thereby causing the machine to be lifted'and supported I by the upward re-action oi the 'air to an extent proportionate to the resistance of thef orward motion of the buckets. The device may be applied to air ships of any suitable construction having any desired means for propelling and steering the machine. Having thusdescribedmy invention,v what I claim as new'and desire to-secure'by Letters Patent is:

"1. An air ship attachment comprising a plurality of buckets rotatable in a horizontal plane, and provided with curved walls extending ln'a quarter circle, -and similar oppositelydisposed s'ector'ends.

2. An air ship attachment comprising-a plurality o! buckets having curved walls extending in'a quarter circle and similar oppositely disposed sector ends mounted upon horizontally rotating arms. I

\ 3. An air ship attachment comprising vertically arplurality of buckets having oppositely disposed secto r ends ,secured to said arms. and curved walls extending in the arc ofa circle.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses;
